M6A-RIP-seq of mRNA in HeLa cells undergoing EMT

ABSTRACT: We report the application of m6A-RIP-seq to indentify the m6A modifications variation in genes invovled in EMT. Briefly, total polyadenylated RNA was isolated from HeLa cells treated with or without 10 ng/ml TGF-β for 3 days by use of TRIZOL reagent followed the using of FastTrack MAGMaxi mRNA isolation kit (Invitrogen). RNA fragmentation, m6A-seq, and library preparation were performed according to instructions of manufacture and the previously published protocol (Wang et al., 2015). NEBNext Ultra Directional RNA Library Prep Kit (New England BioLabs, Ipswich, MA) was used for library preparation. Each experiment was conducted in two biological replicates. m6A-seq data were analyzed according to the protocols described before (Wang et al., 2015). Significant peaks with FDR < 0.05 were annotated to RefSeq database (hg19). Sequence motifs were identified by using Homer. Gene expression was calculated by Cufflinks using the sequencing reads from input samples. Cuffdiff was used to find the DE genes.

Project description:RNA was isolated from control and Mettl3 cKO mouse testes using the TRIzol (Invitrogen) reagent by following the manufactures's instructions. For all samples the RNA integrity was checked using an Agilent Bioanalyzer 2100. All samples showed a RIN (RNA integrity number) of higher than 9. For RNA-seq, approximately 2.5 µg of total RNA was then used for library preparation using a KAPA Stranded mRNA-Seq Kit Illumina® platform (KAPABIOSYSTEMS, KR0960) according to the manufacturer’s protocol.For m6A-miCLIP-seq, 6 ug of mRNA was first fragmented and immunoprecipitated with m6A antibody and thus obtained m6A containing RNA was subjected to cDNA library construction according to previously reported method [Linder et al. 2015; PMID: 26121403].All the libraries were sequenced using HiSeq3000 (Illumina) in paired-read mode, creating reads with a length of 101 bp. Sequencing chemistry v2 (Illumina) was used.

RNA-seq analysis of differentially expressed genes as a function of initial cell-population density during lineage-commitment in mouse embryonic stem cells

Project description:We examined all transcriptome-level expressions in three initial cell-population densities (862, 1724 and 5172 cells/cm2) in the first two days of differentiation in N2B27. We collected cells in 10-mL tubes and centrifuged them using a pre-cooled centrifuge. We then extracted RNA from each cell-pellet using the PureLink RNA Mini Kit (Ambion, Life Technologies) according to its protocol. We next prepared the cDNA library with the 3′ mRNASeq library preparation kit (Quant-Seq, Lexogen) according to its protocol. We then loaded the cDNA library onto an Illumina MiSeq system using the MiSeq Reagent Kit v3 (Illumina) according to its protocol. We analyzed the resulting RNA-seq data as previously described (Trapnell et al., Nat Protoc 2012). We performed the read alignment using TopHat, read assembly using Cufflinks and analyses of differential gene expression data using Cuffdiff. We used the reference genome for Mus musculus from UCSC (mm10). We performed enrichment analysis of genes based on their FPKM values (e.g., more than 2-fold expressed when two initial population densities are compared) by using GO-terms from PANTHER (Mi et al., Nucl Acids Res 2019) and custom MATLAB script (MathWorks). We visualized results of pre-sorted, Yap1-related genes (LeBlanc et al., Elife 2018; Mugahid et al., Elife 2020; Yu et al., Oncogene 2018; Huh et al., Cells 2019; Zhu et al., Nature Sci Rep 2018; Zhou et al., Int J Mol Sci 2016; Vigneron & Vousden, EMBO J 2012; Kim et al., Cell 2015) into heat maps that displays the normalized expression value (row Z-score) for each gene and each condition.

Single-cell RNA-seq of ASPM mutant ferret embryonic forebrain

Project description:As described in our paper "Aspm knockout ferret reveals an evolutionary mechanism governing cerebral cortical size" (Johnson et al., Nature 2018), we used the standard Drop-seq method and analysis of Macosko et al. (2015) to capture, sequence, and analyze mRNA from single cells from Aspm wild-type, heterozygous, and knock-out littermate ferrets at embryonic day 35. Bulk reference samples were processed using standard Illumina mRNA-seq library prep and sequencing protocols, and the samples were described previously (Johnson, Wang et al., Nature Neurosci 2015)

MeRIP-seq of mRNAs in MEFs with or without nutrient starvation

Project description:To investigate the dynamic m6A modification during starvation-induced autophagy, we performed MeRIP-seq in MEFs with or without nutrient deprivation and identified the variations of m6A modification on mRNAs. Briefly, the total polyadenylated mRNAs in MEFs cultured with or without nutrient-deprived medium for 2 hours were isolated using RNAiso plus reagent (Takara) followed Dynabeads mRNA Purification Kit (Invitrogen). The m6A RNA immunoprecipitation was performed using GenSeq m6A RNA IP Kit. NEBNext Ultra II Directional RNA Library Prep Kit (NEB) was used for library generation. Each experiment was conducted in two biological replicates. Methylated sites on peaks were identified by MACS2 peak-calling software (Zhang et al., 2008). Differentially methylated sites were identified by diffReps (Shen et al., 2013) with default setting.

Lignin production associated genes in Cenchrus purpueus

Project description:This study aims to reveal genes related to lignin production in Cenchrus purpureus through RNA-Seq. This species is widely used as forrage for cattle, and for the last years, due to its high biomass yield, has been considered as source to lignocellulosic ethanol. Given those two importances, lignin is a molecule related to low digestibility in cattle and recalcitrance in biofuel production. Eight samples were chosen from previous lignin production and forage quality data; four samples had low lignin production, and four had high lignin production. The highest nodes were collected for RNA extraction using TRIzol reagent, following Jordon-Thaden et a;. (2015) protocol. The cDNA library preparation was generated according to Illumina TruSeq Stranded mRNA Sample Prep kit protocol, and RNA sequencing was performed using HiSeq 2500 sequencer. Quality control was measured by FastQC software v 0.11.8. The sequenced reads were aligned to Cenchrus purpureus genome through STAR software v. 2.5.2b (Dobin et al., 2012). After that, the transcriptome was assembled using Stringtie v 2.0.4 software (Pertea et al., 2015). Salmon v 0.7.2 software (Patro et al., 2017) was used to quantify the sequenced reads. The DEG was identified using DESeq2 package, and genes functions were annotated through Trinotate software (Bryant et al., 2017). In total, approximately 130 million reads were sequenced. The final assembled transcriptome was formed by 101,169 transcripts. The differential expressed genes analysis revealed 52 significatively genes. Here, we highlighted genes related to sterol, L-serine and terpene biosynthetic process.

RNA-Seq analysis of the pancreatic islets from 6-week-old Paupar WT and KO mice

Project description:Transcriptional analysis of the pancreatic islets of adult Paupar KO mice versus Paupar WT mice. Total RNA from Paupar WT and Paupar KO mice was converted into cDNA libraries (TruSeq RNA sample preparation kit, Illumina) according to manufacturer’s instructions. Sequencing was performed to a depth of 30 million, single-end reads in three biological replicates per genotype. Reads were aligned to the mouse genome (mm9) using HISAT2 v2.1.0 (Kim et al., 2013). Aligned reads were assigned to genes using annotations from Ensembl (Mus_musculus.GRCm38.73.gtf) and HTseq-count v0.10.0 (Anders et al., 2015). Differential expression across cohorts was assessed using DESeq2 v1.18 (Love, Huber, and Anders, 2014). Among the downregulated genes with a p-value < 0.05 genes important for alpha cell identity and function.
